JGFMK :
For example. If I have 1234X03.04
I want to capture the 03
and 04
But I don't want 12
, 23
, 34
I understand:
- negative lookahead:
(?!...)
- negative lookbehind:
(?<!...)
But, I don't know how to combine that into a single regex. Can someone help me out? Cheers.
MonkeyZeus :
You can use:
(?<!\d)\d{2}(?!\d)
(?<!\d)
- prior char is not a digit\d{2}
- exactly two consecutive digits(?!\d)
- next char is not a digit
Here's a demo of the results in PHP. I think PHP's regex is close to Java's.
